Just realized it does NOT have dual voltage power adapters (wall plugs).

Sometimes these things tell porkies. The label says one thing but the device knows better.

People have take their life into their hands and tested the thing at the "wrong" voltage. Only to discover that it works for some Netgear adapters. I wouldn't know about your adapter. Maybe someone else has tried it.

I doubt if support can help. Netgear doesn't sell spare adapters. Third party suppliers are all over the place.

Did that power adapter work? I am same situation. All my previous Netgear products were dual voltage. I ordered a new EX7700 extender and its says 120v 50/60hz 12v 1.5A. Most all transformers are dual voltage these days WTF Netgear?

I have been waiting for some madcap experimentalist/gambler to try that.

It has always struck me as odd for Netgear to commission someone to run separate production lines to make adapters. Much easier, and probably cheaper, to churn out the same thing and slap on a local label.
